Re: MDL Locate Filter not always being called for mdlState_startModifyCommand()

I have added the mdlLocate_noElemAllowLocked() and  mdlLocate_setElemSearchMask()
to my command and also removed the restart of the locate in the accept and I
make a call to mdlState_restartCurrentCommand() instead.

What happens now is the element search mask only allows lines which is fine.
My filter is only called when I move over a line element which is ok.
When I accept the element it calls the accept function then the reset.


vHybd_testAccept() IN
hitpath is 6E600E8 ulFilePos=4000038
Element is a line
vHybd_testReset IN
vHybd_testReset OUT
vHybd_testAccept() OUT
iHybd_testFilter() IN
iHybd_testFilter() OUT

Then clicking on the same element straight after I get this. I seem to be unable to
get the accept to trigger again:

vHybd_testReset IN
vHybd_testReset OUT
vHybd_testReset IN
vHybd_testReset OUT
iHybd_testFilter() IN
iHybd_testFilter() OUT
vHybd_testReset IN
vHybd_testReset OUT
iHybd_testFilter() IN


The help says that the mdlState_restartCurrentCommand() restarts the current primative command.
Since I'm using a mdlState_startModifyCommand() I doubt it will be restarting it so I put the
mdlLocate_restart(TRUE) back in the accept.

This lets me select consecutive elements but eventually fails as before;

iHybd_testFilter() OUT
vHybd_testAccept() IN
hitpath is 6E5F178 ulFilePos=4000038
Element is a line
vHybd_testAccept() OUT
iHybd_testFilter() IN
iHybd_testFilter() OUT
vHybd_testAccept() IN
hitpath is 6E5F178 ulFilePos=4000038
Element is a line
vHybd_testReset IN
vHybd_testReset OUT
vHybd_testAccept() OUT
vHybd_testAccept() IN
hitpath is NULL
vHybd_testAccept() IN
hitpath is NULL
vHybd_testAccept() IN
hitpath is NULL
iHybd_testFilter() IN
